Volcan de Chiriqui, and Taboga Island (Champion).—Braziu 2. 
One of the specimens from the Volcan de Chiriqui has the upper surface black, with 
the exception of a common oval yellowish-white patch behind the scutellum and two 
or three light markings on the margins of the tegmina before the apex; it cannot, 
however, be regarded as more than a variety. 
We figure examples from Teapa and Bugaba. 
158. Tettigonia nasuta, sp.n. (Tab. XIX. fig. 28.) 
Preecedenti affinis, sed minor, nigra, nitida ; capite ante oculos haud prominulos longe producto, impresso, ad 
medium leviter carinato; pronoto capite breviori, antice sensim angustato ; tegminibus levibus, macula 
communi ovali pone scutellum, tribusque utrinque ad latera plus minusve triangularibus, albidis ; pedibus 
dilute testaceis. 
Allied to 7. variegata, but at once distinguished by the very long head, which is nearly as long as the pronotum 
and scutellum together, and is broadly impressed and finely keeled longitudinally in the centre; eyes 
scarcely prominent ; upper surface shining black, smooth, with a common yellowish-white oval patch on 
the tegmina just behind the scutellum, and three large white denticulate patches at the margins of the 
sides; legs light testaceous. 
Long. 53 millim.; lat. ad hum, 2 millim. 
Hab. GuatEMata, Vera Paz (Champion). 
This‘may probably be an abnormal variety of 7. variegata, but in its structure it is 
very distinct. 
159. Tettigonia typhlocyboides. 
Tettigonia typhlocyboides, Sign. Aun. Soc. Ent. Fr. 1854, p. 725, t. 21. fig. 11°. 
Hab. Mexico (coll. Germar'). 
This is a very small species, 5 millim. in length, somewhat closely allied to T. variegata, 
but with a shorter and more rounded head and different markings. It is not repre- 
sented in our collection, nor do I know where the type is to be found. 
160. Tettigonia angustula, sp.n. (Tab. XIX. fig. 29.) 
Parva, angusta, parallela, brunnea, fusco vel fusco-nigro plus minusve variegata; capite longo, producto, 
triangulari, testaceo-lineato; fronte flavo-albidd, oculis vix prominulis; pronoto capite breviori; scutello 
magno, flavo-albido, angulis basalibus late fuscis; tegminibus longis, subhyalinis, macula parva elongata 
flavo-albida ad marginem pone medium instructis; abdomine fusco, pectore cum pedibus albidis vel 
flavo-albescentibus. 
A small, narrow, parallel species, brown or fuscous-brown, more or less variegated with darker colour; head
